BACKGROUND

Soybean (Glycine max) is a major grain crop valued for the high levels of oil and protein found in soybean seed. Soybean breeding has resulted in significant improvements in yield potential, stability of yield, adaptation of the species to mechanical harvest, and yield protection through improved disease resistance.

Due to the nature of plant science agriculture, broadly defined as a manipulation of available plant resources to meet the needs of the growing human population, the environment in which plants are grown for agricultural production continuously offers new obstacles to agricultural production. Each new variety, or cultivar, released to agricultural production is selected for the purpose of increasing yield resulting from increased disease resistance to prevalent diseases, or from direct or indirect improvement in yield potential or efficiency of production. Development of stable, high yielding varieties with superior characteristics is an ongoing goal of soybean breeders.

There is a need in the art for a novel, superior soybean variety and soybean seed.

DETAILED DESCRIPTION

In the claims, descriptions, and tables that follow, numerous terms are used and are defined as follows:

Brown Stem Rot (BSR) caused by the fungus, Phialophora gregata, is visually scored from 1 to 9 based on the severity of interveinal leaf chlorosis (yellowing) and necrosis of stems. A score of 1 indicates the most resistance (no symptoms) and a score of 9 indicates the most susceptible.

Canopy width is measured at the widest point of the soybean plant. Visually scored from 1 to 9, where 1=very narrow canopy and 9=extremely bushy canopy.

Charcoal Rot Drought Complex caused by the fungus, Macrophomina phaseolina, is a sandy-soil, mid-summer disease distinguished by gray speckling within the lower stems of soybean plants.

Cotyledon is a type of seed leaf. The cotyledon contains the food storage tissues of the seed. Cotyledon color can be measured as a characteristic of a variety.

Flower color: Modern soybeans are characterized by two major flower colors, purple or white. Some varieties are heterogeneous for flower color whereby some plants have purple flowers and some have white.

Growth habit refers to stem termination in soybeans and the resultant differences in flower production. “Indeterminate” varieties continue to grow during the reproductive phase, producing new branches and nodes after flowering is well underway. “Determinate” varieties tend to delay the onset of flowering somewhat, and limit new node and branch development after flowering has been initiated. “Semi-determinate” varieties continue to produce new vegetative growth during the reproductive phase but growth terminates more quickly than in indeterminate varieties.

Hilum refers to the point of attachment of soybean seed to maternal tissue.

Hilum color in modern soybeans may be black, brown, yellow, gray, buff, or imperfect black.

Iron-Deficiency Chlorosis (IDC) results when soybeans lack adequate iron. A visual score taken 25 to 30 days after planting is used to rate iron-deficiency chlorosis. A score of 1 indicates no stunting of the plants or chlorosis of the leaves, and a score of 9 indicates the plants are dead or dying as a result of iron-deficiency chlorosis. A score of 4.5 means plants have intermediate health with some leaf chlorosis.

Leaflet shape: The leaflet may be broad or narrow and may be lanceolate, ovate or oval in shape.

Lodging relates to the stature of the plant relative to the ground. Lodging resistance is rated on a scale of 1 to 5. A score of 1 is given to an erect plant (lodging resistant). A score of 3 is given to a plant that is leaning at a 45-degree angle relative to the ground. A score of 5 indicates a plant lying on the ground.

Maturity date is the date when 95% of pods have turned color from green color to their mature brown or tan color. The maturity date is counted in days and is calculated from January 1.

Maturity group refers to an industry division of groups of varieties based on the zones in which the varieties are adapted. Soybeans mature differentially in response to day-length and thus to latitude where grown. In the soybean production areas of the United States, for example, the northernmost production region of northern Minnesota is planted to soybeans that mature under very long day-lengths during early summer. In the southernmost production regions of the Southeast, soybeans that mature from the influence of short day-length during early summer are grown. Those adapted to northern day-lengths are classified as early-maturing, those adapted to the southern regions are classified as late-maturing. Maturity groups include very long day length varieties (000, 00, 0) and extend to very short day length varieties (VII, VIII, IX, X). For example, maturity group I soybean varieties are typically grown in southern Minnesota, whereas maturity group IV soybean varieties are typically group in southern Illinois.

Phytophthora “Root Rot” tolerance caused by the fungus, Phytophthora megasperma var. sojae, is rated on a visual scale of 1 to 9, with a score of 1 being the most tolerant and a score of 9 s being the most susceptible to Phytophthora. The visual score is based on the amount of disease-induced stunting of above-ground growth and is taken at harvest.

Plant includes plant cells, plant protoplasts, plant cell tissue cultures from which soybean plants can be regenerated, plant calli, plant clumps, and plant cells that are intact in plants or parts thereof. “Plant part” includes, but is not limited to, embryos, protoplasts, cells, pollen, ovules, cotyledons, hypocotyls, meristems, roots, pistils, anthers, flowers, stems, leaves, pods, petioles, and the like.

Plant height is measured from the top of soil to top node of the plant in any convenient unit of length (i.e., inches, centimeters, etc.). For the data presented herein, plant height was measured just prior to harvest and is expressed in centimeters.

Pod wall color refers to the color of the mature pod wall, as distinct from the color of the pubescence, and in modern soybeans, may be brown or tan.

Pubescence relates to the plant trichomes or hairs found on the stems, leaves and pods of soybeans.

Pubescence color in modern soybeans may be tawny, gray or light tawny.

Relative maturity, within maturity groups, is a more precise maturity assignment that subdivides each maturity group into tenths. For example, a relative maturity of 3.3 is assigned to a late early maturity group III soybean variety.

Roundup Ready 2 tolerance refers to the transgenic soybean event MON89788 from Monsanto Company, as identified in the USDA petition extension No 06-1′780-01p, which imparts glyphosate tolerance to the plant.

Sclerotinia Stem Rot, also referred to as “white mold”, is caused by the soil-borne fungus, Sclerotinia sclerotiorum. Plants are infected via discharged ascospores that successfully germinate and infect through soybean structures such as flower petals. Colonization of stem, pod, and leaf tissue ultimately results in loss of yield potential. Cultivars are rated based on prevalence and severity of a 1 to 9 scale, with 1 being no infection and 9 being severe infection.

Seed coat color refers to the color of the seed coat, and in modern soybeans may be yellow, green, brown or black.

Seed coat luster refers to the luster of the seed coat, and may be dull or shiny.

Seed coat peroxidase activity is defined by a chemical taxonomic technique to separate varieties based on the presence or absence of the peroxidase enzyme in the seed coat. There are two types of soybean varieties, those having high peroxidase activity and those having low peroxidase activity. Ratings are HIGH or LOW for peroxidase enzyme activity.

Seed size is measured by seed number per pound of seed. Seed size is a heritable trait but is influenced by environment, and as such, is often presented as a comparison to another variety.

Shattering refers to pod dehiscence prior to harvest resulting in a loss of mechanically harvestable seed. Pod dehiscence involves seeds falling from the pods to the soil. This is visually scored with a 1 to 9 scale comparing all genotypes within a given test. A score of 1 means pods have not opened and no seeds have fallen out. A score of 5 indicates approximately 50% of the pods have opened, with seeds falling to the ground and a score of 9 indicates 100% of the pods are opened.

Soybean Cyst Nematode (SCN) resistance is based on a comparison of reproduction rates of Heterodera glycines to a known susceptible variety as described by Schmitt et al. (Crop Sci. 32:275-277, 1992), which is incorporated by reference herein. A variety with a 0% to 10% reproductive rate compared to a known susceptible variety is classified as resistant (R); a variety with an 11% to 30% reproductive rate compared to a known susceptible variety is classified as moderately resistant (MR); a variety with an 31% to 59% reproductive rate compared to a known susceptible variety is classified as moderately susceptible (MS).

Soybean emergence scores, also referred to simply as “Emergence,” rate the ability of the seedlings to emerge from the soil. A visual score of 1 to 9, taken from emergence to V3, is used whereby a score of 1 to 3 indicates excellent emergence vigor and early growth, an intermediate score of 5 indicates average ratings, and a score of 7 to 9 indicates a very poor emergence vigor and early growth.

Sudden Death Syndrome (SDS) is caused by slow-growing strains of the fungus, Fursarium solani. The disease is a mid to late season, soil-borne disease in soybean fields. Yield losses may be total or severe in infected fields. The SDS rating is an opportunistic field rating based on leaf area affected. The scale used for these tests is 1 to 9. A score of 1 indicates the most tolerant (least symptoms) and a score of 9 indicates the most susceptible.

Sulfonylurea Tolerance is a herbicide-tolerance trait that improves soybean tolerance to ALS (acetolactate synthase) inhibitor herbicides. Sulfonylurea Tolerant soybeans carry a modified ALS gene, which enhances the variety's natural tolerance to sulfonylurea.

Yield refers to the yield of seed harvested from a soybean crop. Yield data presented herein is expressed as bushels of seed/acre and is the actual yield of the grain at harvest.

Soybean Variety OT16580711 Breeding and Production Methods

The present invention provides methods for producing soybean seed, or plants grown therefrom, by crossing the soybean variety OT16580711 with itself or a second variety. These methods can be used for propagation of the soybean variety OT16580711, or can be used to produce OT16580711-derived hybrid soybean seeds and the plants grown therefrom. Hybrid soybean plants can be used in the commercial production of soy products or may be advanced in certain breeding protocols for the production of additional novel soybean varieties by crossing the soybean variety OT16580711-derived soybean plant with itself or another soybean plant to yield an additional soybean variety OT16580711-derived soybean progeny seed. This crossing process can be repeated one or more times to generate additional soybean varieties. A hybrid plant can also be used as a recurrent parent at any given stage in a backcrossing protocol during the production of the soybean variety OT16580711 which comprises an added desired trait.

In some embodiments, the present invention provides for using the OT16580711 soybean plant, or part thereof, or a soybean plant having the physiological and morphological characteristics of the OT16580711 soybean plant, as a source of breeding material for developing an OT16580711-derived soybean plant in a soybean breeding program using plant breeding techniques. Plant breeding techniques useful in the developing soybean plants include, but are not limited to, single seed descent, modified single seed descent, recurrent selection, reselection, mass selection, bulk selection, backcrossing, pedigree breeding, mutation breeding, restriction fragment length polymorphism enhanced selection, genetic marker enhanced selection, making double haploids and transformation. Plant breeding techniques are known to the art and have been described in the literature. For example, see U.S. Pat. Nos. 6,143,954; 7,803,996; and 7,807,884, which, along with the references cited therein, is incorporated by reference herein.

Selection of soybean plants for breeding is not necessarily dependent on the phenotype of a plant and instead can be based on genetic investigations. For example, one may utilize a suitable genetic marker which is closely genetically linked to a trait of interest. One of these markers may therefore be used to identify the presence or absence of a trait in the offspring of a particular cross, and hence may be used in selection of progeny for continued breeding. This technique may commonly be referred to as “marker assisted selection.” Any other type of genetic marker or other assay which is able to identify the relative presence or absence of a trait of interest in a plant may also be useful for breeding purposes. Procedures for marker assisted selection applicable to the breeding of soybeans are well known in the art. Such methods will be of particular utility in the case of recessive traits and variable phenotypes, or where conventional assays may be more expensive, time consuming or otherwise disadvantageous. Types of genetic markers which could be used in accordance with the invention include, but are not necessarily limited to, Simple Sequence Length Polymorphisms (SSLPs), Restriction Fragment Length Polymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs), DNA Amplification Fingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs), Arbitrary Primed Polymerase Chain Reaction (AP-PCR), Amplified Fragment Length Polymorphisms (AFLPs) (EP 534 858, specifically incorporated herein by reference in its entirety), Simple Sequence Repeats (SSRs, also referred to as “Microsatellites”), and Single Nucleotide Polymorphisms (SNPs).

Many qualitative characters also have potential use as phenotype-based genetic markers in soybeans; however, some or many may not differ among varieties commonly used as parents. The most widely used genetic markers are flower color (purple dominant to white), pubescence color (brown dominant to gray), and pod color (brown dominant to tan). The association of purple hypocotyl color with purple flowers and green hypocotyl color with white flowers is commonly used to identify hybrids in the seedling stage. Differences in maturity, height, hilum color, pubescence color, pod wall color, and pest resistance between parents can also be used to verify hybrid plants.

Soybean variety OT16580711 represents a novel base genetic variety into which a new desired locus or trait may be introduced by introgression. Backcrossing and direct transformation represent two important methods that can be used to accomplish such an introgression. In certain embodiments of the present invention, plants of soybean variety OT16580711 are provided modified to include one or more desired heritable traits.

Plants of the subject invention including one or more desired heritable traits may, in one embodiment, be developed by a plant breeding technique called backcrossing, wherein essentially all of the desired physiological and morphological characteristics of a variety are recovered, when grown in the same environmental conditions, in addition to a genetic locus comprising the desired trait transferred into the plant via the backcrossing technique. Backcrossing methods can be used with the present invention to improve or introduce a desired trait into soybean variety OT16580711. The parental soybean plant which contributes the locus for the desired characteristic is termed the nonrecurrent or donor parent. This terminology refers to the fact that the nonrecurrent parent is used one time in the backcross protocol and therefore does not recur. The parental soybean plant (e.g., soybean variety OT16580711) to which the locus or loci from the nonrecurrent parent are transferred is known as the recurrent parent as it is used for several rounds in the backcrossing protocol (Poehlman et al., 1995; Fehr, 1987a,b; Sprague and Dudley, 1988).

In a typical backcross protocol, the original variety of interest (recurrent parent, e.g., soybean variety OT16580711) is crossed to a second variety (nonrecurrent parent) that carries the single locus of interest to be transferred to produce F1 progeny plants. The resulting F1 progeny from this cross are then selected that have the desired trait and crossed again to the recurrent parent to produce backcross progeny plants having the desired trait and physiological and morphological characteristics of the recurrent parent. The process is repeated until a soybean plant is obtained wherein essentially all of the desired morphological and physiological characteristics of the recurrent parent are recovered in the converted plant, in addition to the transferred locus comprising the desired trait from the nonrecurrent parent.

The selection of a suitable recurrent parent is an important step for a successful backcrossing procedure. The goal of a backcross protocol is to alter or substitute a single or a very limited number of traits or characteristics into the original variety. To accomplish this, a single locus of the recurrent variety is modified or substituted with the desired locus from the nonrecurrent parent, while retaining essentially all of the rest of the desired genetic, and therefore the desired physiological and morphological constitution of the original variety. The choice of the particular nonrecurrent parent will depend on the purpose of the backcross; one of the major purposes is to add some commercially desirable, agronomically important trait to the plant. The exact backcrossing protocol will depend on the characteristic or trait being altered to determine an appropriate testing protocol. Although backcrossing methods are simplified when the characteristic being transferred is a dominant allele, a recessive allele may also be transferred. In this instance it may be necessary to introduce a test of the progeny to determine if the desired characteristic has been successfully transferred.

Soybean varieties can also be developed from more than two parents (Fehr, In: Soybeans: Improvement, Production and Uses, 2d Ed., Manograph 16:249, 1987). The technique, known as modified backcrossing, uses different recurrent parents during the backcrossing. Modified backcrossing can be used to replace the original recurrent parent with a variety having certain more desirable characteristics or multiple parents may be used to obtain different desirable characteristics from each.

Many single locus traits have been identified that are not regularly selected for in the development of a new inbred but that can be improved by backcrossing techniques. Single locus traits may or may not be transgenic; examples of these traits include, but are not limited to, male sterility, herbicide tolerance, insect resistance, modified fatty acid metabolism, modified carbohydrate metabolism and resistance to bacterial disease, fungal disease or viral disease.

Direct selection may be applied where the single locus acts as a dominant trait. An example of a dominant trait is an herbicide tolerance trait. For this selection process, the progeny of the initial cross are sprayed with the herbicide prior to the backcrossing. The spraying eliminates any plants which do not have the desired herbicide tolerance characteristic, and only those plants which have the herbicide tolerance gene are used in the subsequent backcross. This process is then repeated for all additional backcross generations.

In other embodiments of the present invention, plants of the subject invention including one or more desired heritable traits may be developed by direct transformation of soybean variety OT16580711, or through the use of backcrossing approaches as described herein, for example, to introgress a transgenic trait into soybean variety OT16580711. Accordingly, in one embodiment of the present invention a method of producing a plant of soybean variety OT16580711 comprising an added desired trait is provided, where the method comprises introducing at least one transgene conferring the desired trait into variety OT16580711. In some embodiments, introducing at least one transgene conferring the desired trait comprises transforming a soybean plant, or part thereof, of variety OT16580711 with one or more transgenes that confer at least one desired trait. In another embodiment, introducing at least one transgene conferring the desired trait comprises use of backcrossing to introgress a transgenic trait into soybean variety OT16580711. Another embodiment is the product produced by this process, wherein the product comprises the at least one desired trait and all of the physiological and morphological characteristics of soybean variety OT16580711 when grown in the same location and in the same environmental conditions.

In one embodiment the desired trait may be one or more of male sterility, site-specific recombination, abiotic stress tolerance, herbicide tolerance, insect or pest resistance, disease resistance, fungal resistance, modified fatty acid metabolism, and modified carbohydrate metabolism. The specific gene may be any known in the art or listed herein, including: a polynucleotide conferring tolerance to glyphosate, phenoxyacetate auxins, pyridyloxyacetate auxins, phenoxyproprionate auxins, phenoxybutanoate auxins, sulfonylurea, imidazalinone, dicamba, glufosinate, cyclohexone, triazine, and benzonitrile; a polynucleotide encoding a Bacillus thuringiensis polypeptide (e.g. Cry1F and/or Cry1Ac), a polynucleotide encoding phytase, FAD-2, FAD-3, galactinol synthase or a raffinose synthetic enzyme; or a polynucleotide conferring resistance to soybean cyst nematode, brown stem rot, phytophthora root rot, soybean mosaic virus or sudden death syndrome.

Various genetic elements can be introduced into the plant genome using transformation. These elements include, but are not limited to: genes; coding sequences; inducible, constitutive, and tissue specific promoters; enhancing sequences; and signal and targeting sequences. For example, see the traits, genes and transformation methods listed in U.S. Pat. No. 6,118,055. The most prevalent types of plant transformation involve the construction of an expression vector. Such a vector comprises a DNA sequence that contains a gene under the control of or operatively linked to a regulatory element, for example a promoter. The vector may contain one or more genes and one or more regulatory elements.

Plant transformation techniques which result in the generation of transgenic plants are known in the art. These techniques include, but are not limited to:

(1) Projectile bombardment or microprojectile-mediated delivery. This procedure involves propelling inert or biologically active particles complexed with DNA at plant cells, wherein the particles penetrate the outer surface of the cell and the DNA is incorporated within the genome of the plant cell. See e.g., Klein et al., (1987) Nature 327: 70-73; Tomes et al., Plant Cell, Tissue & Organ Culture: Fundamental Methods, eds. Gambourg and Phillips (1995) (Springer-Velag, Berlin); Gordon-Kim et al., (1990) Plant Cell 2:603-618; U.S. Pat. Nos. 4,945,050, 5,879,918, 5,932,782, 5,015,580, 5,550,318, 5,538,880, 6,160,208, 6,399,861, and 6,403,865;

(2) Microinjection of plant cell protoplasts or embryogenic callus, including the use of silicon carbide mediated DNA uptake. See e.g., Crossway et al., (1985) Molecular General Genetics 202:179; Kaeppler et al. (1990) Plant Cell Reporter 9:415-418;

(3) Direct gene transfer. See e.g., International Patent Application No. WO85/01856 and European Patent Application No. 0 275 069;

(4) Electroporation, calcium mediated, or PEG precipitation of protoplasts or cells comprising partial cell walls. See e.g., Fromm et al., (1985) Proceedings of the National Academy of Sciences 82: 5824; Paszkowski et al., (1984) European Molecular Biological Organization 3: 2717-2722; Potrykus et al. (1985) Molecular General Genetics 199:169-177; Shimamoto (1989) Nature 338:274-276; D'Halluin et al. (1992) Plant Cell 4: 1 495-1505; and U.S. Pat. No. 5,384,253.

(5) Aerosol beam technology, which employs the jet expansion of an inert gas as it passes from a region of higher gas pressure to a region of lower gas pressure through a small orifice. The expanding gas accelerates aerosol droplets containing DNA molecules at supersonic speeds into a cell or tissue. See e.g., Held et al., U.S. Pat. Nos. 6,809,232; 7,067,716; and 7,026,286.

(6) Agrobacterium-mediated transformations of plants are also included. Agrobacterium-mediated transformation is described in, for example, Horsch et al., (1984) Science 233:496-498, and Fraley et al., (1983) Proc. Nat. Acad. Sci. USA 80:4803 and U.S. Pat. Nos. 5,824,877; 5,981,840, and 6,384,301; Ishida et al., (1996) Nature Biotechnology 14:745-750. Generally, the Agrobacterium transformation system is used to engineer dicotyledonous plants see Bevan et al (1982) Ann. Rev. Genet 16:357-384; Rogers et al., (1986) Methods Enzymol. 118:627-641). The Agrobacterium transformation system may also be used to transform, as well as transfer, DNA to monocotyledonous plants and plant cells. See U.S. Pat. No. 5,591,616; Hemalsteen et al., (1984) EMBO J3:3039-3041; Hooykass-Van Slogteren et al., (1984) Nature 3 11: 763-764; Grimsley et al., (1987) Nature 325: 1677-179; Boulton et al., (1989) Plant Mol. Biol. 12:3 1-40; and Gould et al., (1991) Plant Physiol. 95:426-434. In addition, gene transfer may be achieved using non-Agrobacterium bacteria or viruses such as Rhizobium sp. NGR234, Sinorhizobium meliloti, Mesorhizobium loti, potato virus X, cauliflower mosaic virus and cassava vein mosaic virus and/or tobacco mosaic virus, See, e.g., Chung et al., (2006) Trends Plant Sci. 1 1(1): 1-4; U.S. Pat. Nos. 6,660,500, 6,462,255, 5,889,190 and 5,889,101.

Soybean transformation is described in particular in a number of publications. An example of an exemplary soybean transformation technique includes the use of Agrobacterium-mediated plant transformation. One example of soybean transformation comprises infecting half-seed explants of soybean with Agrobacterium tumefaciens containing a transgene and regenerating the half-seed explants in vitro on selection medium. See U.S. Pat. No. 7,473,822 and Paz et al., (2006) Plant Cell Reports 25: 206-213. A second example of Agrobacterium-mediated soybean transformation employs the use of glufosinate as the selection system, thereby resulting in an enhanced transformation efficiency. See Zeng et al., (2004) Plant Cell Rep 22:478-482.

After effecting delivery of exogenous DNA to recipient cells, the next steps generally concern identifying the transformed cells for further culturing and plant regeneration. In order to improve the ability to identify transformants, one may desire to employ a selectable or screenable marker gene with the transformation vector used to generate the transformant. In this case, the potentially transformed cell population can be assayed by exposing the cells to a selective agent or agents, or the cells can be screened for the desired marker gene trait.

Cells that survive the exposure to the selective agent, or cells that have been scored positive in a screening assay, may be cultured in media that supports regeneration of plants. In some embodiments, any suitable plant tissue culture media (e.g., MS and N6 media) may be modified by including further substances, such as growth regulators. Tissue may be maintained on a basic media with growth regulators until sufficient tissue is available to begin plant regeneration efforts, or following repeated rounds of manual selection, until the morphology of the tissue is suitable for regeneration (e.g., at least 2 weeks), then transferred to media conducive to shoot formation. Cultures are transferred periodically until sufficient shoot formation has occurred. Once shoots are formed, they are transferred to media conducive to root formation. Once sufficient roots are formed, plants can be transferred to soil for further growth and maturity.

To confirm the presence of a transgene in the regenerating plants, a variety of assays may be performed. Such assays include, for example: molecular biological assays, such as Southern and Northern blotting and PCR; biochemical assays, such as detecting the presence of a protein product, e.g., by immunological means (e.g., ELISA and/or Western blots) or by enzymatic function; plant part assays, such as leaf or root assays; and analysis of the phenotype of the whole regenerated plant.

Through the transformation of soybean, the expression of genes can be altered to enhance disease resistance, insect resistance, herbicide tolerance, agronomic, grain quality and other desired traits. Transformation can also be used to insert DNA sequences which control or help control male-sterility. DNA sequences native to soybean as well as non-native DNA sequences can be transformed into soybean and used to alter levels of native or non-native proteins. Various promoters, targeting sequences, enhancing sequences, and other DNA sequences can be inserted into the genome for the purpose of altering the expression of proteins. Reduction of the activity of specific genes (also known as gene silencing, or gene suppression) is desirable for several aspects of genetic engineering in plants.

Many techniques for gene silencing are well known to one of skill in the art, including but not limited to knock-outs (such as by insertion of a transposable element such as mu (Vicki Chandler, The Maize Handbook ch. 118 (Springer-Verlag 1994) or other genetic elements such as a FRT, Lox or other site specific integration site, antisense technology (see, e.g., Sheehy et al. (1988) PNAS USA 85:8805-8809; and U.S. Pat. Nos. 5,107,065; 5,453,566; and 5,759,829); co-suppression (e.g., Taylor (1997) Plant Cell 9:1245; Jorgensen (1990) Trends Biotech. 8(12):340-344; Flavell (1994) PNAS USA 91:3490-3496; Finnegan et al. (1994) Bio/Technology 12: 883-888; and Neuhuber et al. (1994) Mol. Gen. Genet. 244:230-241); RNA interference (Napoli et al. (1990) Plant Cell 2:279-289; U.S. Pat.

(2000) Plant Cell 12:691-705; and Baulcombe (1999) Curr. Op. Plant Bio. 2:109-113); target-RNA-specific ribozymes (Haseloff et al. (1988) Nature 334: 585-591); hairpin structures (Smith et al. (2000) Nature 407:319-320; WO 99/53050; and WO 98/53083); MicroRNA (Aukerman & Sakai (2003) Plant Cell 15:2730-2741); ribozymes (Steinecke et al. (1992) EMBO J. 11:1525; and Perriman et al. (1993) Antisense Res. Dev. 3:253); oligonucleotide-mediated targeted modification (e.g., WO 03/076574 and WO 99/25853); Zn-finger targeted molecules (e.g., WO 01/52620; WO 03/048345; and WO 00/42219); and other methods or combinations of the above methods known to those of skill in the art.

Exemplary nucleotide sequences or encoded polypeptides that may be altered or introduced by genetic engineering to provide desired traits include, but are not limited to, those categorized below.

1. Genes or Encoded Proteins that Confer Resistance to Pests or Disease.

(A) Plant Disease Resistance Genes. Plant defenses are often activated by specific interaction between the product of a disease resistance gene (R) in the plant and the product of a corresponding avirulence (Avr) gene in the pathogen. A plant variety can be transformed with cloned resistance gene to engineer plants that are resistant to specific pathogen strains. Examples of such genes include, the tomato Cf-9 gene for resistance to Cladosporium flavum (Jones et al., 1994 Science 266:789), tomato Pto gene, which encodes a protein kinase, for resistance to Pseudomonas syringae pv. tomato (Martin et al., 1993 Science 262:1432), and Arabidopsis RSSP2 gene for resistance to Pseudomonas syringae (Mindrinos et al., 1994 Cell 78:1089).

(B) A Bacillus thuringiensis protein, a derivative thereof or a synthetic polypeptide modeled thereon, such as, a nucleotide sequence of a Bt δ-endotoxin gene (Geiser et al., 1986 Gene 48:109). Moreover, DNA molecules encoding δ-endotoxin genes can be purchased from American Type Culture Collection (Rockville, Md.), under ATCC accession numbers, e.g., 40098, 67136, 31995 and 31998. Other non-limiting examples of Bacillus thuringiensis transgenes being genetically engineered are given in the following patents, patent applications and publications and hereby are incorporated by reference for this purpose: U.S. Pat. Nos. 5,188,960; 5,689,052; 5,880,275; 5,986,177; 7,105,332; 7,208,474; WO 91/14778; WO 99/31248; WO 01/12731; WO 99/24581; WO 97/40162 and U.S. application Ser. Nos. 10/032,717; 10/414,637; 11/018,615; 11/404,297; 11/404,638; 11/471,878; 11/780,501; 11/780,511; 11/780,503; 11/953,648; 11/953,648; and Ser. No. 11/957,893, and Estruch, et al., 1996.

Proc. Natl. Acad. Sci. 93:5389.

(D) A vitamin binding protein, such as avidin and avidin homologs which are useful as larvicides against insect pests. See U.S. Pat. No. 5,659,026.

(E) An enzyme inhibitor, e.g., a protease inhibitor or an amylase inhibitor. Examples of such genes include, a rice cysteine proteinase inhibitor (Abe et al., 1987 J. Biol. Chem. 262:16793), a tobacco proteinase inhibitor I (Huub et al., 1993 Plant Molec. Biol. 21:985), and an α-amylase inhibitor Sumitani et al., 1993 Biosci. Biotech. Biochem. 57:1243).

(F) An insect-specific hormone or pheromone such as an ecdysteroid and juvenile hormone a variant thereof, a mimetic based thereon, or an antagonist or agonist thereof, such as, baculovirus expression of cloned juvenile hormone esterase, an inactivator of juvenile hormone (Hammock et al., 1990 Nature 344:458).

(G) An insect-specific peptide or neuropeptide which, upon expression, disrupts the physiology of the affected pest. Examples of such genes include, an insect diuretic hormone receptor (Regan, 1994), an allostatin identified in Diploptera punctata (Pratt, 1989), insect-specific, paralytic neurotoxins (U.S. Pat. No. 5,266,361).

(H) An insect-specific venom produced in nature by a snake, a wasp, etc., such as, a scorpion insectotoxic peptide (Pang, 1992 Gene 116:165).

(I) An enzyme responsible for a hyperaccumulation of monoterpene, a sesquiterpene, a steroid, hydroxamic acid, a phenylpropanoid derivative or another non-protein molecule with insecticidal activity.

(J) An enzyme involved in the modification, including the post-translational modification, of a biologically active molecule; for example, glycolytic enzyme, a proteolytic enzyme, a lipolytic enzyme, a nuclease, a cyclase, a transaminase, an esterase, a hydrolase, a phosphatase, a kinase, a phosphorylase, a polymerase, an elastase, a chitinase and a glucanase, whether natural or synthetic. Examples of such genes include, a callas gene (PCT published application WO93/02197), chitinase-encoding sequences (which can be obtained, for example, from the ATCC under accession numbers 3999637 and 67152), tobacco hookworm chitinase (Kramer et al., 1993 Insect Molec. Biol. 23:691) and parsley ubi4-2 polyubiquitin gene (Kawalleck et al., 1993 Plant Molec. Biol. 21:673).

(K) A molecule that stimulates signal transduction. Examples of such molecules include, nucleotide sequences for mung bean calmodulin cDNA clones (Botella et al., 1994 Plant Molec. Biol. 24:757) and a nucleotide sequence of a maize calmodulin cDNA clone (Griess et al., 1994 Plant Physiol. 104:1467).

(L) A hydrophobic moment peptide. See U.S. Pat. Nos. 5,659,026 and 5,607,914, the latter teaches synthetic antimicrobial peptides that confer disease resistance.

(M) A membrane permease, a channel former or a channel blocker, such as, a cecropin-β lytic peptide analog (Jaynes et al., 1993 Plant Sci. 89:43) which renders transgenic tobacco plants resistant to Pseudomonas solanacearum.

(N) A viral-invasive protein or a complex toxin derived there from. For example, the accumulation of viral coat proteins in transformed plant cells imparts resistance to viral infection and/or disease development effected by the virus from which the coat protein gene is derived, as well as by related viruses. Coat protein-mediated resistance has been conferred upon transformed plants against alfalfa mosaic virus, cucumber mosaic virus, tobacco streak virus, potato virus X, potato virus Y, tobacco etch virus, tobacco rattle virus and tobacco mosaic virus. See, for example, Beachy et al. (1990) Ann. Rev. Phytopathol. 28:451.

(O) An insect-specific antibody or an immunotoxin derived therefrom. Thus, an antibody targeted to a critical metabolic function in the insect gut would inactivate an affected enzyme, killing the insect. For example, Taylor et al. (1994) Abstract #497, Seventh Int'l. Symposium on Molecular Plant-Microbe Interactions, shows enzymatic inactivation in transgenic tobacco via production of single-chain antibody fragments.

(P) A virus-specific antibody. See, for example, Tavladoraki et al. (1993) Nature 266:469, which shows that transgenic plants expressing recombinant antibody genes are protected from virus attack.

(Q) A developmental-arrestive protein produced in nature by a pathogen or a parasite. Thus, fungal endo α-1,4-D polygalacturonases facilitate fungal colonization and plant nutrient release by solubilizing plant cell wall homo-α-1,4-D-galacturonase (Lamb et al., 1992) Bio/Technology 10:1436. The cloning and characterization of a gene which encodes a bean endopolygalacturonase-inhibiting protein is described by Toubart et al. (1992 Plant J. 2:367).

(R) A developmental-arrestive protein produced in nature by a plant, such as, the barley ribosome-inactivating gene has an increased resistance to fungal disease (Longemann et al., 1992). Bio/Technology 10:3305.

2. Genes that Confer Tolerance to a Herbicide.

(A) Genes encoding resistance or tolerance to a herbicide that inhibits the growing point or meristem, such as an imidazalinone or a sulfonylurea. Exemplary genes in this category code for mutant ALS (Lee et al., 1988 EMBOJ. 7:1241) and AHAS enzyme (Miki et al., 1990 Theor. Appl. Genet. 80:449).

(B) One or more additional genes encoding resistance or tolerance to glyphosate imparted by mutant EPSP synthase and aroA genes, or through metabolic inactivation by genes such as GAT (glyphosate acetyltransferases or GOX (glyphosate oxidase) and other phosphono compounds such as glufosinate (PAT and bar genes), and pyridinoxy or phenoxy proprionic acids and cyclohexones (ACCase inhibitor encoding genes). See, for example, U.S. Pat. No. 4,940,835, which discloses the nucleotide sequence of a form of EPSP which can confer glyphosate tolerance. A DNA molecule encoding a mutant aroA gene can be obtained under ATCC accession number 39256, and the nucleotide sequence of the mutant gene is disclosed in U.S. Pat. No. 4,769,061. European patent application No. 0 333 033 and U.S. Pat. No. 4,975,374 disclose nucleotide sequences of glutamine synthetase genes which confer tolerance to herbicides such as L-phosphinothricin. The nucleotide sequence of a phosphinothricinacetyl-transferase gene is provided in European application No. 0 242 246. De Greef et al. (1989) Bio/Technology 7:61 describes the production of transgenic plants that express chimeric bar genes coding for phosphinothricin acetyl transferase activity. Exemplary genes conferring tolerance to phenoxy proprionic acids and cyclohexones, such as sethoxydim and haloxyfop, are the Accl-S1, Accl-S2 and Accl-S3 genes described by Marshall et al. (1992) Theor. Appl. Genet. 83:435.

(C) Genes encoding resistance or tolerance to a herbicide that inhibits photosynthesis, such as a triazine (psbA and gs+ genes) and a benzonitrile (nitrilase gene). Przibilla et al. (1991) Plant Cell 3:169 describes the use of plasmids encoding mutant psbA genes to transform Chlamydomonas. Nucleotide sequences for nitrilase genes are disclosed in U.S. Pat. No. 4,810,648, and DNA molecules containing these genes are available under ATCC accession numbers 53435, 67441 and 67442. Cloning and expression of DNA coding for a glutathione S-transferase is described by Hayes et al. (1992) Biochem. J. 285:173.

(D) Genes encoding resistance or tolerance to a herbicide that bind to hydroxyphenylpyruvate dioxygenases (HPPD), enzymes which catalyze the reaction in which para-hydroxyphenylpyruvate (HPP) is transformed into homogentisate. This includes herbicides such as isoxazoles (EP418175, EP470856, EP487352, EP527036, EP560482, EP682659, U.S. Pat. No. 5,424,276), in particular isoxaflutole, which is a selective herbicide for maize, diketonitriles (EP496630, EP496631), in particular 2-cyano-3-cyclopropyl-1-(2-SO2CH3-4-CF3 phenyl)propane-1,3-dione and 2-cyano-3-cyclopropyl-1-(2-SO2CH3-4-2,3Cl2phenyl)propane-1,3-dione, triketones (EP625505, EP625508, U.S. Pat. No. 5,506,195), in particular sulcotrione, or else pyrazolinates. A gene that produces an overabundance of HPPD in plants can provide tolerance or resistance to such herbicides, including, for example, genes described at U.S. Pat. Nos. 6,268,549 and 6,245,968 and U.S. publication No. 20030066102.

(E) Genes encoding resistance or tolerance to phenoxyacetate auxin herbicides, such as 2, 4-dichlorophenoxyacetic acid (2,4-D) and which may also confer resistance or tolerance to “fop” herbicides. Examples of such genes include the α-ketoglutarate-dependent dioxygenase enzyme (AAD-1) gene, described at U.S. Pat. No. 7,838,733.

(F) Genes encoding resistance or tolerance to phenoxyacetate auxin herbicides, such as 2, 4-dichlorophenoxyacetic acid (2,4-D) and which may also confer resistance or tolerance to pyridyloxyacetate auxins (such as fluroxypyr and triclopyr), phenoxyproprionate auxins (such as MCPA and dichloprop), phenoxybutanoate auxins (such as 2,4-DB). Examples of such genes include the α-ketoglutarate-dependent dioxygenase enzyme (AAD-12) gene, described in U.S. Pat. No. 8,283,522.

(G) Genes encoding resistance or tolerance to dicamba, such as dicamba monooxygenase (DMO) from Pseudomonas maltophilia which is involved in the conversion of a herbicidal form of the herbicide dicamba to a non-toxic 3,6-dichlorosalicylic acid and thus may be used for producing plants tolerant to this herbicide. See, e.g., U.S. Patent Application No: 20030135879.

3. Genes that Confer or Contribute to a Value-Added Trait.

(A) Modified fatty acid metabolism, for example, by transforming maize or Brassica with a small RNA or stearoyl-ACP desaturase to increase stearic acid content of the plant (Knultzon et al., 1992) Proc. Nat. Acad. Sci. USA 89:2624.

(B) Decreased phytate content

(1) Introduction of a phytase-encoding gene would enhance breakdown of phytate, adding more free phosphate to the transformed plant, such as the Aspergillus niger phytase gene (Van Hartingsveldt et al., 1993 Gene 127:87).

(2) A gene could be introduced that reduces phytate content. In maize, this, for example, could be accomplished by cloning and then reintroducing DNA associated with the single allele which is responsible for maize mutants characterized by low levels of phytic acid (Raboy et al., 1990 Maydica 35:383).

(C) Modified carbohydrate composition effected, for example, by transforming plants with a gene coding for an enzyme that alters the branching pattern of starch. Examples of such enzymes include, Streptococcus mucus fructosyltransferase gene (Shiroza et al., 1988) J. Bacteriol. 170:810, Bacillus subtilis levansucrase gene (Steinmetz et al., 1985 Mol. Gen. Genel. 200:220), Bacillus licheniformis α-amylase (Pen et al., 1992 Bio/Technology 10:292), tomato invertase genes (Elliot et al., 1993), barley amylase gene (Sogaard et al., 1993 J. Biol. Chem. 268:22480), and maize endosperm starch branching enzyme II (Fisher et al., 1993 Plant Physiol. 102:1045).

(D) Altered antioxidant content or composition, such as alteration of tocopherol or tocotrienols. For example, see U.S. Pat. No. 6,787,683, US2004/0034886 and WO 00/68393 involving the manipulation of antioxidant levels, and WO 03/082899 through alteration of a homogentisate geranyl geranyl transferase (HGGT).

(E) Altered essential seed amino acids. For example, see U.S. Pat. No. 6,127,600 (method of increasing accumulation of essential amino acids in seeds), U.S. Pat. No. 6,080,913 (binary methods of increasing accumulation of essential amino acids in seeds), U.S. Pat.

No. 5,559,223 (synthetic storage proteins with defined structure containing programmable levels of essential amino acids for improvement of the nutritional value of plants), WO 96/01905 (increased threonine), WO 95/15392 (increased lysine), US2003/0163838, US2003/0150014, US2004/0068767, U.S. Pat. No. 6,803,498, WO 01/79516.

4. Genes that Control Male-Sterility.

There are several methods of conferring genetic male sterility available, such as multiple mutant genes at separate locations within the genome that confer male sterility, as disclosed in U.S. Pat. Nos. 4,654,465 and 4,727,219 to Brar et al. and chromosomal translocations as described by Patterson in U.S. Pat. Nos. 3,861,709 and 3,710,511. In addition to these methods, Albertsen et al., U.S. Pat. No. 5,432,068, describe a system of nuclear male sterility which includes: identifying a gene which is critical to male fertility; silencing this native gene which is critical to male fertility; removing the native promoter from the essential male fertility gene and replacing it with an inducible promoter; inserting this genetically engineered gene back into the plant; and thus creating a plant that is male sterile because the inducible promoter is not “on” resulting in the male fertility gene not being transcribed. Fertility is restored by inducing, or turning “on”, the promoter, which in turn allows the gene that confers male fertility to be transcribed.

(A) Introduction of a deacetylase gene under the control of a tapetum-specific promoter and with the application of the chemical N-Ac-PPT (WO 01/29237).

(B) Introduction of various stamen-specific promoters (WO 92/13956, WO 92/13957).

(C) Introduction of the barnase and the barstar gene (Paul et al. Plant Mol. Biol. 19:611-622, 1992).

For additional examples of nuclear male and female sterility systems and genes, see also, U.S. Pat. Nos. 5,859,341; 6,297,426; 5,478,369; 5,824,524; 5,850,014; and 6,265,640; all of which are hereby incorporated by reference.

Soybean Products

Soybean is useful not only as a seed for producing soybean plants, but also has utility as a grain. The grain can be used as a food source for both animals and humans. Soybean is widely used as a source of protein for animal feeds for poultry, swine and cattle. The soybean grain is therefore a commodity. The soybean commodity plant products include but are not limited to protein concentrate, protein isolate, soybean hulls, meal, flower, oil and the whole soybean itself.

During processing of whole soybeans, the fibrous hull is removed and the oil is extracted. The remaining soybean meal is a combination of carbohydrates and approximately 50% protein. For human or animal consumption soybean meal is made into soybean flour that is processed to protein concentrates used for meat extenders or specialty pet foods. Production of edible protein ingredients from soybean offers a healthy less expensive replacement for animal protein in meats as well as dairy-type products.

Accordingly, the present invention includes in some embodiments methods for producing a commodity plant product, which comprise obtaining seed of soybean variety OT16580711 and producing the commodity plant products disclosed above. The invention further comprises soybean commodity plant products derived from soybean variety OT16580711 seed according to these methods.
